: Hi. I am going to sign a new lease in a new place in the next few weeks. My girlfriend will likely be moving in with me from Chicago in January. Are there any considerations I should take into account with regard to my lease (she will not be on it)? That is, can I just have her move in with me or is it the landlords business too?

: Thanks for your help

Check your lease. Usually, it will say that no one can stay with you over a period of time (usually 3 days) without permission from the landlord. If your landlord finds out someone is living with you who is not on the lease, you will be in violation of your lease and may be evicted.
